Hello:

Can someone expound on the meaning of the numbers that are used in the
AIP Particle Properties Data Booklet for the bosons that mediate EM,
the weak force, and the strong force?

photon
I = 0,1
J^PC = 1--
m < 3 x 10^-33 MeV (1992)
W
J = 1
m = 80.22 GeV
Z
J = 1
m = 91.17 GeV
g or gluon
I = 0
J^P = 1-
m = 0

J is intrinsic angular momentum, the same for all three. Apparently,
one thinks about parity when considering J, why I am not clear. What
is I, and the meaning of I=0 versus I=1? Why is there no I value for
the W and the Z (my guess: the non-zero mass)? How do we know the
gluon has a mass of zero if one has not been observed due to
confinement?

Thanks,
doug

Odd PC means that the mote or whit can carry net angular and linear
momentum, respectively[, I reckon].

I is isospin, which applies to the up and down quarks and their
hadròns. The I=1 I think means the fotòns can interact between thwart-
flavor whole-charge mesòns, lik u'd'. W and Z need whole flavors to
work.

The gluòn must be, if nuclear interactions are to be fast (as in fast,
not swift that everyone corrupts intom) and quarks don't decay. A
fundamental forse must not be mediated by composite particula;
otherwise they together would leave a mass.
